Here's a list of all the Path programs that didn't fill in the match, with total number of positions available in the match and number of unfilled positions.  I did not include any data from programs that were listed as AP- or CP-only.  If I'm counting right that makes 17 unfilled positions total, which I believe is lower than average for Pathology.
Penrose Hospital (Colorado Springs, CO)  2 positions, 1 unfilled
Northwestern  5 positions, 2 unfilled
University of Chicago/Northshore  3 positions, 1 unfilled
Berkshire Medical Center (Springfield, MA)  1 position, 1 unfilled
Dartmouth-Hitchcock Medical Center  2 positions, 1 unfilled
Stony Brook  5 positions, 3 unfilled
University of Rochester/Strong Memorial  4 positions, 1 unfilled
Pitt County Memorial Hospital/Brody School of Medicine (Greenville, NC)  3 positions, 2 unfilled
Wake Forest Baptist Medical Center  4 positions, 1 unfilled
West Res Care/NEOUCOM-OH (Youngstown, OH)  1 position, 1 unfilled
